i was getting the following error while taking database backup
[root@solr7 ~]# mysqldump -u root -p**** ostn>ostn
mysqldump: Couldn’t execute ‘SELECT @@GTID_MODE’: Unknown system variable ‘GTID_MODE’ (1193)
This error is in part due to the introduction of Global Transaction Identifiers (GTIDs) in MySQL 5.6. GTIDs make it simple to # track and compare replication across a master-slave topology. mysqldump tries to query this system variable, which doesn’t exist in earlier versions, and then fails.
